( 1)a & gt； 1 0 & lt； 1/a & lt； 1 y = (1/a) x is the subtraction function images b and d.

Y=loga(-x) is the domain x < 0 and there is no image after fixed point (-1, 0).

(2)0 & lt； a & lt 1 1/a & gt； 1 y = (1/a) x is the increasing function images a and c.

Y=loga(-x) is the domain x < 0 of the increasing function and passes through that fixed point (-1, 0).

So choose C.
